ssio r H 5 The hopper is thus yielfib'ly The hopper is provided centrally between its ends and intermediate the top and bottom with symmetrical openings one of whichserves as an intake and the other as an outlet for the material to be treated. Extending about the lower portion of one opening on the outside of the.

hopper is the material receiving scoop 21, while similarly disposed relative to the other open-" ing is an outlet trough or chute 22. The chute minimize the wear on the same due to the heavy matter, discharged onto said chute and to catch any precious metal particleswhich might pos siblybe discharged along with the residue. V

Inside and adjustably secured, to the side walls of the hopper V are horizontally movable wear plates adapted to be moved toward and from Mounted in the hopper in transversely spaced the open sides of, the corresponding opening. The plates of thedischarge opening are normal- :1y.,set so that their edges project inwardly of the opening somewhat as shown in Fig. 1, and thus take the abrasive wear of the discharging material which otherwise would be imparted directly to the side walls of the hopper about ,the edge of the opening. The plates are removable so that when wom back as far astheir.

adjustment permits they may be easily and cheaply replaced. f

relation a short distance below theopenings 20 are longitudinally extending bars 26 which support removable rectangular grids 27. The grids are of heavy and wear resisting material such as I manganese steel. and are provided with upstanding spikes 28, at the corners of the grid openings. The grids are clamped in place at their ends by transverse bars 29vover the same and which are secured to the supporting bars 26 by cap screws 30V or the like. A relatively fine mesh screen 31 covers the entire horizontal area of the hopper immediately under the. grids and between said grids and the bars 26-and extends up the en d w,alls a certain distance as. shown. v.;'I'he grids extend from side to side of the hopper but-occupy only the. central longitudinal portion of the same, the screen between the ends vof the grids and the endwalls of the hopper place are horizontal splash plates 33. These.ex-

tendthefull width of the hopper from said end walls toward each other and terminatfi substantially in the vertical planes of the opposed edges of the clamping bars 29. p 3 g t a s I The rear end wall of the hopper at the bottom and centrally'of its width is provided with a relatively small outlet opening 34 with which a vertically adjustable gate 35 is associated. The gate ison the outside of the wall but inside a removable-lidded box 36 which projects from the hopperand into which the outlet 34 opens.- Transversely spaced discharge spouts 37 project from .the outer end of the box, the fiow from the :outlet 34 being distributed evenly to the spouts by .reason of. a vertical baffle plate 38. disposed in the box intermediate the spouts and outlet, and

extending transverselvot .said box. This arrangement is for use with a two unit concentrator. If a single unit is employed only one centrally located spout will be necessary as will be evident.

In operationv the material to be treated is dumped'into the scoop 21 from a suitable supplychute above the same and separate therefrom. Such material passes into the hopper through the adjacent opening 20, a certain quantity of water suflicient to keep the grids constantly covered being fed into the hopper as well. With the longitudinal and vertical shaking of the hopper the material is violently agitated and thrown about, the water sloshing back and forthwith a wave-like action with great force,

being prevented from splashing out of the hopper by the end splash plates 33.

The movement of the ,waterquickly separates the graveLsand and the like from thefheavy and lergestones, etc. and causes this small material to be discharged through the screen 31 at various points of its area into the lower portion of the hopper, from which it is carried through theoutlet by the flow of water also passing through said outlet. With this movementI-of' the water such light material is thrown against the end wallsof the hopper, the heavy screening 32 acting to prevent thefadhesion of any appreciable amount of material such as clay to the walls or the screen 31. Ithus prevent suchan accumulation of material of this kind on the walls as would ultimately chokeup the screen andbe detrimental to the desired separating and disintegrating action. I Theheavy stones, large pieces of quartz etc. while thrown about by the shaking action of the hopper and the movement of the water are re- .tained on the grids. The constant up and down and longitudinal jerking of the hopper. causes the stones etc. to be brought into violent contact with the grid spikes and with the grids themselves. As a result any quartz and similar fracturable pieces are thoroughlydisintegrated and broken up. into small fragments capable of passing through the screen 31.

After the material has been thus disintegrated and has dropped through the screen 31 it passes through the outlet 34 along with a constant but limited flow of water as previously indicated and is delivered with such water to the concentrator for the separation of any precious content therenot disintegrated by the shaking of the hopper ultimately pass through the upper discharge outlet 20'of the hopper whence they are delivered by the chute 22 to a dumpheap.

The disintegrated and separated material is delivered by the spouts 37 onto the intake troughs 40 of a double unit concentrator 41'. This may be of any suitable construction but is preferably of the shaking type such as is; shown in my'Patent No. 1,679,035. While the concentrator itself forms no part of this present invention, still it is transverse plates 43 secured to the, beams 1 and inclined lengthwise thereof as shown in Fig.6.

The shaft 8 is disposed under the troughsv 40 (which extend ahead of the concentrator proper) 50 from. The large. valueless stones etc. which are 4 and has an eccentric 44 of a lesser stroke than the eccentrics '7 disposed centrally on said shaft between the bearings 9. This eccentric is preferably set on the shaft in opposed relation to the eccentrics 7 so as to aid in balancing the shaft.

A strap 45 engages the eccentric 44 and a rod 46 projects horizontally from said strap and through a cross beam 47 extending transversely of and secured to the concentrator at its forward end. A compression spring 48 is disposed about said rod between the forward face of the cross beam and a collar 49' on the rod. A heavy resilient bumper block 50 through which the rod passes is disposed against the back face of the beam 47 and is engaged on its rear end by a cap 51. A vertical transversely extending spring band 52 is mounted at its opposite ends on bolts 53.

which are secured to certain of the concentrator frame elements 54; said band being disposed between the cap 51 and the end nut 55 on the rod 46. g

The resilient block provides a flexible mounting for the rod and absorbs vibrations which would otherwise be imparted to the concentrator with the forward stroke of the eccentric rod. The spring 48 gives a yieldable cushioned movement to the concentrator with the back stroke of the eccentric, which is aided by the spring band 52 which prevents the block from jumping away from the cross beam. In this manner the concentrator is given a smooth shaking action without any severe vibrations such as might be detrimental to its efiicient functioning.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:
